LATCH.

Application fil ed June 4, 1926. Serial No. 113,777.

This invention aims to provide a simple mechanism for latching sliding doors, the device being so made that it may be operated either from within or from without the door, and thcstructure being adaptable for use upon either a single or a double door, or upon a left hand door or a right hand door.

Itv is within the province of the disclosure to improve generally and to enhance the utility of devices of that type'to which the invention appertains,

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may ,be made within the Scope of what is claimed, without departing from the spirit of the invention.

' In the drawings Figure 1 shows in elevation, a device constructed in accordance with the invention;

Figure 2 is a longitudinal section wherein parts appear in elevation;

Figure 3 is a sectional elevation showing a modification.

The numeral. 1 denotes a support for the mechanism hereinafter described, and in the present application of the invention, the support 1 is in the form of a sliding door, adapted to cooperate with a amb 2. On the door 1 is mounted a bracket, including a base plate 3 equipped at its inner end with an outstanding stop 4. There is an opening 5 in the base plate 3, the opening being dispose-d closely adjacent to the stop 4-. The door 1 has an opening 6 lined up with the opening 5 in the base plate 3. The base plate 3 of the bracket has laterally extended feet 7 which, as shown in Figure 1, are attached by securing elements 8 to the door 1, the base plate of the bracket thus being held an approximately horizontal position on the door. Intermediate its ends, the base plate 3 has outstanding ears 9 connected by a pivot element 10, such as a bolt, on which a latch 11 is pivotally mounted intermediate its ends, the latch extending between the ears 9. The latch 11 has a loopshaped outstanding handle 12 and has, also,

7 an operating member 14 in the form ot'a stem, the operating member 14 and the handle 12 projecting in opposite directions,

the operating member or stem 14 extending through the opening 5 in the base plate 3, and terminating in a head 15 that is disposed in the opening 6 of the door 1. The latch 11 has an outwardly curved end 16 provided with a hole 17, there being a transverse shoulder 18 at the inner end ofthe part 16 of the latch. A. guide pin 19 projects from the base plate 3 of the bracket and is received slidably in an opening 20 formed in the latch 11. A compression spring 2l-surrounds the guide pin 19, one end of The keeper includes a carrying plate 22 held by securing elements 23 and 24 on the j amb 2, the carrying plate 22 being equipped at one end witha curved overhanging finger 28, and being supplied at its opposite end with an inclined flange 25 having elongated slots 26. The numeral '27 marks a supplemental plate disposed parallel to the carrying plate 22 and supplied atone end with a curved overhanging finger 29, and at its other end is provided with an inclined flange 30 Which lies against the flange 25 of the carrying plate 22. Securing devices 31, such as bolts, are mounted in the slots 26 of the flange 25 of the carrying plate 22 and are adjustable therein, the securing devices being mounted in the inclined flange 30 of the supplemental plate 27. An angle member 32 is provided, one flange of the angle member being connected by a securing device 33 with the supporting plate 27. The outstanding wing of, the angle member 32 has a hole 34:.

When the door 1 is slid to a closed position, the shoulder 18 on the latch 11 engages automatically with the part 29, as shown in Figure 2. Through the openings 17 and 3 1,

may be placed a seal, lock, or other securing device. The handle 12 affords a means whereby thelatch 11 may be operated from one side of the door, and the stem 14 and the button 15 afford a means whereby the latch may be operated from the opposite side of the door. The adjustment provided at 2631 enables the supplemental plate 27 to be adjusted transversely, with respect to the carrying plate 22, thereby to change the distance between the plate 27 and the outer surface of the jamb 2, so that the doors 1 of different thicknesses may be accommodated.

In Figure 3, parts hereinbefore described, have been designated by numerals previously used with the suffix a. In Figure 3, the latch mechanism is mounted on one sliding door 35, and the keeper mechanism is mounted on another sliding door 36 which abuts at its edge against the door 35. In this form of the invention, the supplemental plate 27 of Figure 2 is detached. The carryingplate 22 is turned end for end from the position shown in Figure 2. The-shoulder 18 of the latch engages with the finger 28".

The part 25 becomes a handle whereby the door-36 may be operated. The angle member32 is'retained on the carrying plate 22 by the securing device 33 which holds the parts 22 and 32 on the door 36.

What is claimed is A keeper of the class described, comprising a carrying plate and a supplemental plate provided at their outer ends with latch-engaging fingers, the plates being arranged in opposltely-projecting approximately parallel relation and being supplied at their inner ends with overlapped angular flanges, means for connecting the flanges adjustably to accommodate the keeper to doors of different thicknesses, and detachably whereby the carrying plate can be turned end for end and used alone, an out standing member having an opening for the reception of a latch-engaging securing device, and means for mounting said member on either plate at the will of an operator.

In testimony thatI claim the foregoing as my oWn, I have hereto affixed my signature. I
